So do I. But the datatype is NOT URI, it's a URI reference.

They are allowed, just "deprecated" by a separate note.

It *is* a URI reference. Just because the W3C later decided that relative
URI references shouldn't be used doesn't make every legal namespace name a
URI.

For instance, the namespace name "http://greenbytes.com#reference"; is
perfectly ok (it's not relative), yet it's a URI reference, not a URI. Thus
(as you said), I think it's wrong to talk about the "namespace URI". It may
not be a URI.
